IMPROVEMENT IN BEDSTEAD-FASTENINGS.

Specification forming partof Letters Patent No. 209,022, datcdOctober15, 1878; application filed March 29, 1878.

To all whom it may concern 7 Be it known that I, LEVIN P. CLARK, of thecity of Baltimore and State of Maryland, have invented certainImprovements in Bedstead- Fastenings, of which the following is aspecification and I do hereby declare that in the same is contained afull, clear, and exact description of my said invention, reference beinghad to the accompanying drawing, and to the letters of reference markedthereon.

This invention relates to certain improvements in that class of bedsteadfastenings wherein provision is made for drawing together the two partsof the bedstead after their connection; and its object is to efi'ect avermin-proof joint between the bed post and rail, as will hereinafterfully appear,

In the description of the said invent-ion which follows, reference ismade to the accompanying drawing, forming a part hereof, and in which-Figure 1 is a side view of a part of a bedstead rail and post connectedbymeans of my improved device, portions of the wood-work and the innerplate of the device being re moved. Fig. 2 is a transverse section ofFig. 1 on the dotted line ar Fig. 3 is a face view of a part of theinvention.

Similar letters of reference indicate similar parts in all the figures.

A is the casing or outer plate of the main member of the fasteningdevice, secured by means of screws to the inner side of the rail 3, andG the inner plate, secured to the outer one, A, by means of rivets,screws, or similar appliances. D is a bolt, which, when the device is inuse, connects the two parts or members of the fastening device, andholds the post and rail together. The secondary member, E, of the deviceis aflixed to the bedpost F, and consists in a thimble having a flangeor projection, over which the end of the bolt D is hooked. The inner endof the bolt D, confined within the casing A, is increased in width, andprovided with an opening, a, in

which is located the mechanism for moving the bolt to and from thebed-post. This mechanism consists in an eccentric, d, supported by hubse, which penetrate the plates A and (J, and a lever, f, attached to oneof the hubs, to be used in turning the cam. The movement of the cam d insuch direction as to efl'ect the tightening of the joint between thepost and rail is communicated to the bolt D through the medium of avibratory link, g, one end of which rests in a circular depression inthe bolt.

To unite the bed post and rail, the bolt B is first extended or forcedoutwardly to its eX- treme limit by means of the eccentric d, and

the outer end of the said bolt, which is hooked, inserted in the thimbleE, secured to the post. The eccentric is then turned in an oppositedirection, which causes the post and rail to be drawn tightly together.

In order to reduce the strain upon the screws holding the casing A tothe rail B, in the operation of the device, a block, G, is secured tothe said rail, against which the end of the said casing next to thebed-post F bears, the said block being slotted to admit of the passagethrough it of the bolt. Upon the rail being brought into contact withthe post, a pin, h,

projecting from the end of the rail, enters a small thimble in the post,which serves to maintain the rail and post in their proper relativepositions, while the fastening is completed by means of the devicesbefore described.

Having thus described my invention, what I claim as new, and wish tosecure b Letters Patent, is-

The casing A, eccentric d, link g, and sliding bolt D, in combinationwith the thimble E.

In testimony whereof I have hereunto subscribed my name this 29th day ofJanuary, in the year of our Lord 1878.
